A further object of the invention is to enable a plurality of churn-dashers to be simultaneously operated for churning in a plurality of churn bodies or receptacles and to provide a system of springs adapted to operate successively to assist both the up and down movement of the churn-dashers.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted'to without departing from the spiritor sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a churn constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional View of thesame. Fig. 3 is a vertical transverse sectional view. Fig. 4: is a horizontal sectional view on the line 4 4. of Fig. 3. Fig. 5 is a horizontal sectional view on the line 5 5 of Fig. 3. Fig. 6 is a detail view of one of the cross-heads. Fig 7 is a detail view illustrating another means for securing the dasher rods or stems to the crossheads.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 1 designate similar churn bodies or receptacles provided with covers 2, having central openings, through which pass dasher rods or stems 3 of dashers 4. The churn bodies or receptacles, which may be of any desired construction, are provided at the central openings of their covers with upwardly-extended funnels 5, adapted to return to the churn any liquid carried upward by the dasher-rods. Thecovers of the churn bodies or receptacles may be secured in place by hooks 6 or any other suitable fastening device, and the funnels may be mounted on the covers in any desired manner. The churn bodies or receptacles are arranged within acabinet or casing 7, which protects them from dust during the operation of churning and which are provided at the front and back with bearings 8, arranged in pairs and receiving the ends of similar fourthrow crankshafts 9. Each four -throw crank-shaft is provided with a central crankbend 10 and a pair of diametrically oppositely arranged crank-bends 11, and the said shaft is also provided at each side of the central crank-bends 10 and 11 with side crank-bends 12 and 13, arranged in planes at right angles to the planes of the central crank-bends l0 and 11. The side crank-bends 12 and 13 are arranged at diametrically opposite points, as clearly shown in Fig. 1 of the drawings. The dashers reciprocate in opposite directions and are reversely arranged, as shown in Fig. 2, whereby when one dasher is at the limit of its upward movement the other dasher will be at the limit of its downward movement. Four pairs of coiled springs are employed for assisting the operation of each dasher and are successively brought into action by the rotation of the four-throw crank-shafts. The fourthrow cranks are reversely arranged, and the central double crank-bends 10 extend in opposite directions when they are disposed horizontally, as shown in Fig. 1. The dasherrods, which have their upper ends reduced, are secured by removable pins or keys 14 in central openings 15 of cross-heads 16. When it is desired to remove the churn body or receptacle after the operation of churning has been completed, the pin or key 14 is removed and the dasher drops to the bottom of the churnbody. The cabinet or casing is provided at each end with a door 17, hinged at theback and having a suitable fastening device at the front and adapted to afford access to, the interior of the cabinet or casing. The cross head 16 is located centrally above the churnbody; and its ends 18 are reduced and arranged in vertical ways of the casing or cabinet. The

inner faces of the front and rear walls of the The springs which are secured to the cross heads of the dashers tend to draw the same downward, and thereby effect the downstroke of the dashers. The cross-heads are connected by cords with the crank-bends of. the crankshafts, as hereinafter explained, and when the crank-shafts are rotated the springs will be successively brought into action to assist the reciprocation of the dasher, and as soon as one set of springs becomes inert another set will be thrown into action, four sets being operated at each revolution of the'crankshaft. When the dasher is down, as shown at the right-hand end of Figs. 1 and 2 of the drawings, the central double loop of the corresponding crank-shaft is arranged horizontally and is extended outward. This central crankcords 27 with the outer cross-head 20. The

cords of the crank-shaft at the left-hand end of the churn in Fig. 2 are arranged in the positions, or rather in a corresponding position, when the dasher is at the lowermost limitof its strokethat is, when the double crank 10 is extended horizontally to the right in Fig. 2 the central crank 10 will be reversed and will extend to the right. The cords 28 will then extend vertically to the adjacent cross-head 22, and the cords 29 of the diametrically opposite crank-bends will then extend vertically to the adjacent outermost cross-head 21. The cords 30 of the dasher cross-head are connect ed to one set of the vertically-alined cranks, and the cords 31 of the adjacent outer crosshead 30 are connected with the outer set of the vertically-alined cranks. However, as shown in Fig.2, at the left-hand end thereof the cords are reversed by reason of the crankshaft being disposed in a diametrically opposite position from that of the crank-shaft at the right-hand end of the churn.

The crank-shafts have keyed or otherwise secured to their ends pinions 32, which mesh with gear wheels 33, located between the pinions, as clearly shown in Fig. 1, and adapted to cause the crankshafts to rotate in the same direction. The front gear-w heel meshes with a gear 3& of a shaft 35, which may, as illustrated in the drawings, be provided with a crank-handle 36, but which may be operated by any other suitable means. Instead of operating the churn by hand a suitable power -may be employed, as will be readily understood. When the crank-handle is rotated, the crank-shafts with which the springs are connectedwill be simultaneously rotated in the same direction, and the dashers will be reversely reciprocated, and the four sets of springs of each crank-shaft will be successively brought into action during each revolution,

and as rapidly as one set of springs becomes inactive another set will be brought 1nto action,and both the upward and downward movementof the dasher will be assisted. The upward movement of the dasher results directly from the upward pull of the central crankbend, which is connected with thedasher by the flexible connection, and the downward movement of the dasher results directly from the springs, which are connected to the crosshead of the dasher. The dominant spring, or the spring under the greatest tension, as soon as it passes over the top imparts a sudden im-- pulse to the dasher either by suddenly'pulling upward on the dasher or suddenly releasing the flexible connection of the dasher, and an irregular or interrupted reciprocatory motion is produced, which results in a great agitation of the contents of the churn-body. This irregular reciprocation and the consequent agitation of the contents of thechurn-bocly greatly facilitate the production of butter.

The cross-heads, which are connected to the dashers, are limited in their downward movement to prevent them from striking the funnels by means of stops 37 consisting of strips covering the lower portions of the adjacent ways.

. The shaft 35 is provided with the balancewheel 35 which is mounted on the shaft, as clearly shown in Figs. 3 and 4. This balance-wheel, which is shown at the front of the casing, may be located at any other desired point. Also the mechanism may be employed for operating washing-machines and devices other than churns.

In Fig. 7 of the accompanying drawings is illustrated another means for securing the dasher rods or stems to thecros's-heads. The cross-head 38 is provided with a movable section 39, hinged at one end and secured at the other end by a hook and eye or other suitable fastening device. The movable section and the body portion of the cross-bar are provided with similar recesses or grooves to form the opening for the dasher rod or stem, which is provided with an annular groove to form upper and lower shoulders for engaging the cross-head.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
